Correction to: Environmental Earth Sciences (2020) 79:331 https://doi.org/10.1007/s12665-020-09093-1

The original article has been published inadvertently with some errors in figures and their caption (Figs. 1, 2, 3, 5) and errors only in captions of figures (Figs. 4, 6, 7, 8, 9), also errors in tables and their caption (Tables 1, 5, 6, 7) and errors only in captions of tables (Tables 2, 3). All the corrected versions of figures and tables (with captions) are given below.

Fig. 1

Regional settings of the Subarnarekha deltaplain and position of palaeo-shorelines. Within the Subarnarekha river basin (a) the study area situated in the ancient delta fan region (b). The positions of river course in the downstream section of Rajghat (c) and in Asti section (d) have been considered for micro-morphological change analysis of the channel unit

Fig. 2

Landscape composed of upper (> 12 m), middle (7–9.5 m), and lower (< 7 m) terraces in the lower Subarnarekha river basin. Palaeo meander scrolls aligned over middle-lower terraces. Five different areas of total station survey (TSS 1 to 5) have been indicated by rectangles. AA′, BB′ and CC′ are the position of cross-valley transects for analysis of micro-landforms
